REGISTER.

SPECIFICATION forming part of Letters Patent No. 741,126, dated October13, 1903.

Application led October 25. 1902. Serial No. 128,716. (No model.)

To @ZZ wiz/0m t may concern:

Be it known that I, HYMAN ELI GOLDBERG, a citizen of the United States,residing in the city of Chicago, county of Cook, State of Illinois, haveinvented a new andruseful Improvement in Registers, of which thefollowing is a specification.

My invention relates to registers, especially of the class used incalculating-machines, a register of this type being shown in a separateapplication for Letters Patent filed by me in the United States PatentOffice on the 1st day of October, 1900, Serial No. 31,666.

The object of the present invention is to provide a simple andpositive-acting tens-carrying device and is attained by the mechanismillustrated in the accompanying drawings, in which- Figures 1 and 2 aretop and side views, respectively, of the complete registering mechanism.Figs. 3 and 4 are fragmentary views drawn to an increased scale andshowing the relative position of the registers, tens-storing wheels, andtens-carrying disks. Said Fig. 3 is a view taken from the top, and Fig.4 is a view taken from the side on the line 44, Fig. 3. Fig. 5 is a sideView of the complete tensstoring wheel, and Figs. 6 and 7 are views ofthe component parts thereof. Figs. 8, 9, 10, and 11 are diagrammaticviews drawn to an increased scale, illustrating the mode of operation ofthe registers, tens-storing Wheels, and tens-carrying disks.

Similar numerals refer to similar parts throughout the several views.

The registers 1 consist of disks of similar sine mounted side by side onthe shaft 2 so as to rotate independently of each other. Said registersare provided with the teeth 3,whereby they may be rotated. Said teethoccupy a portion only of the Width of said registers, the remainingcylindrical portion 4 having, by preference, marked thereon the figures0 to 9 in one or more series for registering totals in the manner usualin this class of machines. Said teeth are some multiple of ten in numberand occupy a position upon the right of the register, so that the teeth3 of one register are adjacent to the register corresponding to the nextlower digital place. The points of the teeth 3 preferably do not projectabove the cylindrical portion 4 of the registers, but are substantiallyflush with the same. The tens-carrying teeth 5 are formed at one or morepoints in the cylindrical portion 4 of the registers for the purposehereinafter described. The point at which said teeth are locatedcorresponds to a Zero-point on the register, there being as many sets ofteeth 5 on each register as there are series of figures thereon. Saidteeth 5 are formed at the left portion of the registers and preferablyproject slightly beyond the cylindrical face thereof. Said registersrotate independently, but always in the same direction, about the shaft2, said shaft being fixed in the side plates 6, which form the frameworkof the device.

The first step in the operation of this mechanism is to set up a numberon the registers by rotating them individually, each one the correctamount, without reference to the carrying of the tens. The second stepis to impart a supplemental rotation to the registers to take intoaccount any tens which may have to be carried. This supplementalrotation is accomplished by means of the tens-carrying device. In otherwords, by means of the tenscarrying device a ten upon any given registeris at the proper time transferred, so as to register a unit on the nexthigher register. In the carrying of the tens the registers are actuatedby the tens-storing wheels 7, and

these in turn are actuated by the carryingdisks 12. Said tens-storingwheels consist, preferably, of two portions or parts 9 and 10, which maybe formed separately and subsequently brazed or otherwise securedtogether or may be constructed of a single piece. Said parts 9 and lOare shown separately in Figs. 6 and 7, respectively. The part 9 consistsof a toothed wheel mutilated by having a number of teeth thereof cutaway and the remaining teeth located adjacent to each other andpreferably two in number. Part l0 consists of an arm projecting beyondthe point-circle of the gear-wheel 9 and extending in a differ'- entdirection from the teeth of said wheel.

A suitable construction of the tens-storing Wheel as assembled is shownfrom the side in Fig. 5, said figure showing a mutilated fivetoothedwheel having but two teeth remaining, and the arm 10 extending on aradius angularly in advance of the said teeth ap- ICO cro

proximately three-tenths of a circumference. The tens-storing wheels areloosely mounted on the shaft 11, so as to rotate independently thereon,and the parts are so assembled that the teeth of the mutilated gear 9may mesh with the register-teeth 5 and at other times contact theregister-surface 4. The arm 10 is in a location to engage the teeth 3 onthe next higher register, and the distance between the curved surface 4of the register 1 and the axis of the tens-storing wheels 7 is less thanthe radius of the point-circle of the mutilated gear-wheel 9. By thisconstruction the teeth of the said part 0 abut against said surface 4and prevent the rotation of the said storing- Wheel. The arm 1U extendsin such a direction and is of such length as not to interfere with theregisters l when' the teeth of the part 10 are locked between the saidregisters and the carrying-disk 12, the location of the parts being`best indicated in Fig. 3. The said shaft l1 is mounted in the sideplates 6, and so, also, is the axle 13; but said axle is freelyrevoluble, and all of the disks 12 are rigidly secured thereto, so thatall rotate as asingle piece.

One or more gear-teeth 14 are formed in the periphery of the disks 12,the number depending upon the construction of the mulilated gear-Wheel9. In the present case there is but one complete tooth 14, which isadapted to enter between the two teeth of said mutilated live-toothedwheel. The remaining portion 15 of the periphery of the disk 12 ispreferably cylindrical. Said curved surface 15 approaches the axis ofthe tens-storing wheel 7 to within a distance less than the radius ofthe point-circle of the part 9 of the said wheel, thereby preventing therotation of said wheel when said curved surface is in conjunction withthe-teeth thereof, but rotating said wheel when the teeth 14 are in meshwith the teeth upon the part 9.

Located, preferably, upon the side of the disk l2, but in such aposition as to engage the arm l0 of the storing-Wheel, is the arm or lug16, so placed as to occupy a position in front of the teeth 14 withrespect to the direction of rotation ot' said disk 12.' The purpose ofthe arm 16 is to insure the engagement of the teeth 14 with the teeth ofthe part 9 of the storing-wheel.

The registers 1, tens-storing Wheels 7, and the disks 12 are soconstructed and placed that a wheel 7 is locked by the curved surfacesof the said adjacent members; but if the teeth 5 of the register engagethe. said storing-Wheel the latter is rotated to such a position as tobe engaged by the teeth 14 and arm 16 of said disk l2. Moreover, therotation of said storing-Wheel by said disk 12 causes the said arm 16 torotate the next higher register one figure, thereby carrying the ten.

The carrying-disks 12 are arranged in a series upon the axle 13 andconstitute the carrying-drinn of the machine. The teeth 14 of onecarrying-disk are one step in advance of the teeth 14 of the next highercarrying-disk, which arrangement produces upon the carrying-drum theresemblance of a helix or screw, and thereby causes the rotation of thetensstoring wheels 7 seratm, so as to carry from units place first,highest place last. The rotation of said carrying-drum is accomplishedby means of the crank 17 on the axle 18 or in any other suitable manner.

In operation the registers are first rotated individually by anysuitable means, so that each register will have been turned the correctnumber of steps without reference to Whether the next lower register hasor has not completed a tens series and passed a zeropoint; but to arriveat the right result in case any register has completed a ten the tenmust be subsequently transferred or carried as a unit onto the nexthigher register. This carrying is accomplished by turning the crank 17,and thereby rotating the axle 13 and the tens-carrying drum fixedthereto. Suppose that the registers have been set up individuallythat isto say, each has been rotated a definite amount from its prior position,but without reference to whether or not any tens have been completedupon any of the other of the registers. When such preliminary setting uphas been accomplished, such of the registers as have completed a tenhave by means of the teeth 5 rotated the tens-storing wheel 7 from thelocked position shown in Fig. 8 to the locked position shown in Fig. 10.The last-mentioned position is such that the arm 10 of the tens-storingwheel Will be engaged by the arm 16 of the disk 12 when the latter isrotated; In order now 1o complete the carrying of the tens, the axle 13is rotated by means of the crank 17, the result being that the arm 16and the tooth 14 on the disk 12 strike the arm 10 and then the teeth 9of the storing-wheel 7, and thus complete its rotation, bringing it tothe original position and locking it; but the arm 10 of this storing-Wheel meshes during said rotation with the teeth 3 of the register, andthis rotates said register one step. These last two steps areillustrated in Figs. lO and 11. If during the first step in setting up aregister has been rotated, but not far enough to carry a ten, suchregister will not have aected its storing-Wheel, and therefore saidstoring-wheel will not be affected by any rotation of the disk 12. Thisis illustrated in Fig. 9. Although to assist in the understanding ofthis mechanism it has been referred to as part of a calculating-machine,it may be used in other connections, and therefore I do not limit myselfto a mechanism for use in calculatingmachines merely.

What I claim as new, and desire to secure by Letters Patent, is-
